PE pipes are currently developing in China's municipal pipe market, and PE pipes, PP-R pipes, and PVC pipes go hand in hand, among which the strong development momentum of PET is the most eye-catching, and polyethylene (PE) pipes have high impact resistance and will not crack or break during installation and transportation.　Polyethylene (PE ) piping is made of sunscreen carbon stabilizer, which can be placed outdoors or used outdoors for a long time without worrying about changes in piping performance.

PET pipes can be divided into: solid wall pipes and corrugated pipes.

Bellows also include hollow wall, plastic steel winding, double wall corrugation, steel belt reinforcement, and the most commonly used on the market are plastic winding and steel belt pipe.

PE steel belt reinforced spiral corrugated pipe has many names in the industry, also known as steel belt reinforced spiral bellows, steel belt spiral bellows is usually directly called steel belt pipe.

Today, Xiaobian will analyze the difference between steel strip pipe and plastic steel winding pipe for you.

The same is a star product of sewage discharge, and steel strip pipe and PE plastic winding pipe are often compared with each other, because the outer wall of the pipe is a crest, and the two are often confused, and even feel that there is little difference between the two. With the familiarity and understanding of the industry, it is found that there is a certain correlation between the two pipelines, but there are also great differences. The differences between the two are as follows:

1. The compression capacity is different. The plastic winding has a stronger uneven settlement capacity than the steel strip tube, the steel strip has a stronger vertical root ring stiffness, and the steel strip tube has a lower compression capacity of the steel strip in an arc. Because the construction site is a waterway, the geological conditions are not good, and the use of plastic winding pipes as construction materials greatly improves the quality of the project.

2. The thickness of the strip is different. The strip selected in the plastic wound pipe is Q235 strip (the thickness of the plastic wound DN1800 strip is 3.0 mm, and the strip reinforcing pipe is 1.5 mm), and after the thickness is increased, it is not easy to deform and crack the pipe under any geological conditions.

3. The connection method is different.

The steel strip pipe connection method mainly adopts four connection methods: hot melt extrusion welding, electric hot melt band connection, heat shrinkable pipe (belt) connection and coupling.

The plastic spiral wound pipe connection method is stainless steel clamp and hot melt tape connection, and the stainless steel clamp is the most common of the two methods.

4. Other applicable scopes

Steel belt pipes are mainly used in municipal drainage and sewage pipe networks, filtrate collection pipes in sewage treatment plants, industrial sewage discharge pipes, filtrate collection pipes in garbage treatment plants, highway drainage pipes, pipes for optical cable covering, seawater pipes, etc.

Plastic winding pipes are mainly suitable for pipes that can replace high-energy materials (cement, cast iron, ceramics, etc.), and are environmentally friendly products.
